Y SWITCH Filed Jan. 17; 1951 20 j g I 2/ 4/ If Inventor E. 14 Fasmussen A Home y Patented Sept. 13, 1932 UNITED STATES EDWIN WILLIAM RASMUSSEN, 0F DENMARK, WISCONSIN SWITCH Application filed January 17, 1931. Serial No. 509,504.

This invention appertains to new and useful improvements in switches and more particularly to a switch especially adapted for use in the usual automobile electrical sys- 5 tem.

The principal object of the present invention is to provide a switch whereby the battery can be shut ofi from the electrical de vices of the automobile, so that there will be substantially no likelihood of a short occurring with the incidental possibility ofconflagration.

During the following specifications and claims, other important objects and advantages of the invention will readily become apparent to the reader.

In the drawing V Figure 1 presents a diagrammatic view disclosing the device in the battery in circuit.

Fig. 2 represents a longitudinal sectional view through the novel switch.

Fig. 3 represents a transverse sectional view through the switch.

Referring to the drawing wherein like numerals designate like parts, it canbe seen in Fig. 1, that numeral 5 represents the usual automobile battery from which the current supply lead 6 extends.

The switch comprises a base plate 7 upon which is mounted the casing 8. The casing 8 is lined by di-electric sheets 9. Extending through the top portion of the casing 8 are the binding posts 10 and 11, each of which is provided at its lower end with a contact head 12, adapted to be bridged by the conductor plate 13, which slides 14 operative by the element 15 which extends to a point adjacent the drivers seat, where it is provided with a knob 16.

A follower plate 17 is urged upwardly within the casing 8 by the leaf spring 18 for normally maintaining the conductor 13 I urged into a position against at least one of the contacts 12. Interposed between the casing 8 and the bracket 19 and between the casing 8 and the nut 20 on the post 10 is the di-electric body 21 which has its intermediate portion oifset to provide an upstanding flange 22.

Thebracket 19 is provided witha longitudinally extending slot 23 whereby the switch can be adjustably supported in any to without departing from the spirit and scope of the invention as claimed hereinafter;

Having thus described my invention, what I claim as new is 1. A switch of the character described comprising a casing, a pair of contacts in the casing, a slide, a contact plate on the slide for engagement with the contact, means for urging the conductor plate into engagement with at least one of the said contacts, said means comprising a di-electric follower plate which is positioned against one side of the slide, and a spring for urging the follower against the slide.

2. A switch of the character described comprising a casing having a di-electric lining, a pair of contacts at the inside of the lining, a contact plate slidable through an opening in the casing and adapted to bridge the contact when slid to an operated position, a dielectric follower plate pressing against the contact plate, and a spring for urging the follower plate in a direction at right angles to the operative motion of the contact plate for maintaining the contact plate tensionally urged toward the contact.

In testimony whereof I aflix my signature.

EDWIN WILLIAM RASMUSSEN.
